how to make an object look wet in Eevee? (blender 2.8.3 at least)
For a very simple, fast and easy to do effect, I just had to:

In edit mesh mode I used &quot;face/shade smooth&quot;, so no need to subdivide the mesh (wouldnt be enough anyway).
change Roughness to about 0.125, even w/o a texture.

It looks good.
Not sure tho if it could cause trouble later to try to apply other effects (not that I am trying to).
It is only visible in &quot;Viewport shading&quot; &quot;render preview&quot; mode.
